Generally, the fillers used according to the invention are colorless or white, ie non-pigmentary, that is to say they are not used to impart a particular color or hue to the composition according to the invention, even if their use can inherently lead to such a result. These fillers serve in particular to modify the rheology or the texture of the composition.

As such, they are, in this respect, distinct from nacres, organic pigment materials such as, for example, carbon black, D & C type pigments, and lacquers based on cochineal carmine, barium, strontium, calcium, aluminum. and inorganic pigment materials such as, for example, titanium dioxide, zirconium or cerium oxides, as well as iron oxides (black, yellow or red) or chromium, manganese violet, ultramarine blue, hydrate chromium and ferric blue, which are used to provide a hue and color effect to the compositions incorporating them.

Such compounds are not covered, within the meaning of the invention, by the definition of charges which therefore cover non-pigmentary fillers that may be organic or inorganic. The non-pigmentary fillers used in the compositions according to the present invention may be of lamellar, globular, spherical, fiber-like, or any other form intermediate between these defined forms.

EXAMPLE N ⁰ 1 Preparation of Siloxane Resins

The following resins are used:

Resin MQ = an MQ resin of formula M _o , ₄ 3Qo, 57 and M _n = 3230 dissolved in xylene at 70.8% by weight solids. The MQ resin was manufactured according to the techniques described by Daudt in US Patent 2,676,182.

Propyl resin T = a propyl resin silsesquioxane 74.8% by weight in toluene. Silsesquioxane propyl resin was obtained by hydrolysis of propyl trichlorosilane.

Preparation of MQI ^Pr resins

An MQ resin, a propyl resin T, xylene and 1M KOH in water in the proportions shown in Table 1 are introduced into a three-neck equipped with a stirrer, a temperature probe and a a Dean Stark apparatus equipped with a condenser at the top. Xylene is pre-introduced into the Dean Stark apparatus to ensure a 50% solids level is maintained in the reactor. The mixture in the reactor is maintained at a reflux temperature (between 100 and 140 ^° C.) for at least 3 hours. Any water forming in the reaction mixture is removed continuously if necessary and entrapped as an azeotrope in the Dean Stark apparatus. After refluxing for 3 hours, water is removed from the apparatus and heating is continued for another 30 minutes. After cooling the mixture, an excess of acetic acid is added to neutralize the KOH in the mixture. The mixture is then filtered in order to remove the salts formed by passing it through a pressure filter. Solvent exchange is achieved by heating the mixture in a rotary vacuum evaporator. After removal of the majority of the xylene, decamethylcyclopentasiloxane or isododecane is added while continuing to remove any residual aromatic solvent. The structures of the resulting siloxane resins are characterized by ²⁹ Si and CPG NMR spectroscopy and the results are summarized in Table 2 below. Table 1
